Disk-wheel for road-vehicles.

DISK WHEEL FOR RO-AD VEHICLES.

APPLICATION FILED MAY 7, 1906.

To allwhom it may conceive:

Be it known that I, EDWARD MARTIN, a

- subject of the King of England, residing a l Thisinvention refersto an improved diskfor carrying a solid tire with a U-shaped 61 Newland Terrace, Queens -Road,-Batt ersea, in the-county of London, England, have invented certain new and useful Improve ments in Disk-Wheels for Road yehicles; and I do hereby declare the following to be a full, clear, and exact description of the inven- .tion, such as will enable others skilled inthe 'art to which it appertains to make and use the same.

wheel for road-vehicles, which wheel isespecially applicable for use with a pneumatic tire, but which may be used with advantage "I cover.

It is well known that one of the reasons why. neumatic tires burst, especially when attac ed to motor-bars, is that the-interior inflated chamber of-the tire is so small compared with the pressure which'it has to sus-.

' tain that a sudden shock often puts too se vere 'a strain upon the cover. It has been suggested from time to time to relieve this pressure by putting the inner chamber of the tire in connection :With a flexible fluid-containing chamber, located, for instance, in the case of a disk-wheel between the disks; .but

extreme difficulty-has been experienced in providing a suitablebag for containing the air-and in making all the joints'air-tight, and in order that my said invention may be j better understood]. will now. proceed to describe the same with reference to the draw? ings accompanying this specification, in

I to denote the same parts in both the views.

a b aredisks ofsteel or other suitable ma- 'terial, which are dished or shaped as shown at Fig. 1, for the reception of the various parts of the Wheel and-tire.

c is an intermediate portion made, preferably, of aluminium for the sake of lightness and provided with transverse holes.

.12 and f show portions of an ordinary artilg shows bolts for passing through holes in the disks (1 b, the intermediate portion 0, and

the hub portions 6 andffor holding the whole firmly together. '1

aluminium or other suitablematerial faced with an iron band 2', provided with project.- inggedg'es or headings y', or such projecting edges or headings may be formed on the ring it itself, the band i being dispensed with.

7c is a ,tire of iU'shape.

m represents bolts which" pass through the edges of the tire 7:, andthi'ough the-ring h for holding the whole in 'positi on.

n represents holes'passing radially through the ring it in order to allow a free passage for formed, between the disks to the tire. l -0 isa valve of ordinary construction.

the interior of tuted for the pneumatic tire 7c, in which case it-is unnecessary to-fill' the chamber formed by thedisks with air." w A pneumatic disk-whee] constructed as herein described is fafmoreresilient than the ordinary tire, owing to the increased size of .the air-chamber, while at the same time there is less liability to puncture and the life ofthe tireis increased. Moreoverflzhere is less dust thrown up from the road, owing to the absence of the fan-like action produced by the s okes and the greatly-reduced size of the tree. of the tire.

What I claim, and desire to secure by Letters Patent of the United States of America,

1. A disk-wheel, comprising a pair of side spacing-ring disposed between .said disks at t eir peripheral edges, said ring adapted to have a pneumatic tire secured thereto, with said apertures in communication with the interior of the tire, the -whole constructed to form an air-tight chamber within said wheel, in communication withthe interior of. the pneumatic tire,substantially as described.

disks bolted together with an inner middle ortion at the hub of the'wheel and a circumterential ring portion provided with radial holes,- in combination with a pneumatic tire,

\ the cover of which is belted between the edges of the disks and. the circumferential 'whee and the interior of thepne'umatic tire may form one air-tight chamber in connec holes in the edges of the disks a b,'.through,

' When desired, a solid tire may be substi disks securely spaced apart centrally and- I converging "outwardly, and an apertured ring ortion so that the interior of the diskh is a circumferential ring ,which takes the i I place of a felly. This ring may be made of -the,--air from the interior of the chamber 2. A pneumatic disk-wheel comprising two IIO and a circumferential ring portion of a tire rovided with a U-shaped cover, such cover ei bolted between the disks and the circum erential ring portion substantially as described.

4.' In a disk-wheel the combination with a pair of side disks disposed parallel centrally and provided with an internal spacing member, hub members, and means for securely holding same together, said disks converging outwardly from said central spacing member and terminating at their peripheral edges in an annular recess, a ring member disposed within said recess and provided with a plurality of radially-disposed apertures adapted to form communicating passages between the interior of a of said whee and means for securing the coverof said tire between said disks and an-- nular ring, substantially as described.

In testlmony whereof I aflix my signature in presence of two witnesses.

EDWARD MARTIN.
